We just stayed for the first time in Nov. and were happy - love CSR as well, that is our favorite Moderate! Agree with PP - loved Broadway section - so cool to see at night! Great theming, and closest to lobby after preferred buildiing. You can call and add room request - we did Broadway Building 8, top floor, close to lobby - we had Touring Plans service, so requested 8655 by their fax, and got 8659(from one or the other!) You can check out the ASMu thread on resorts forum to see pics and details.
Just be aware you have two double beds vs queens at CSR, and room is a little smaller. We brought a cheap over-the-door style shoe organizer with plastic pockets from Walmart, to hang at end of closet (nearest sink) to keep toiletries in, which helps sink space stay clear(also good at CSR which only has one sink). Also no hot tubs or slides at Values, which you will have at CSR. You are definitely doing the resorts in the right order, but think you will enjoy both!
